Dosing considerations for Lemon Eucalyptus.

The following doses have been studied in scientific research:

APPLIED TO THE SKIN:

For preventing mosquito bites: a 30%, 40%, or 75% lemon eucalyptus oil solution. However, the higher concentration does not seem to be more effective than the lower concentration. Commercial products available in the US (e.g., Repel Lemon Eucalyptus) contain 10% to 30% lemon eucalyptus oil. Directions on these products suggest applying the oil no more than twice per day. Be sure to wash your hands thoroughly after applying the oil. Avoid getting it on your lips or into your mouth.

For preventing ticks from attaching and biting: A specific 30% lemon eucalyptus oil extract (Citriodiol) has been applied up to three times daily when exposed to tick infested areas. This specific extract is used in commercial products such as Mosi-guard and Repel Oil of Lemon Eucalyptus. Be sure to wash your hands thoroughly after applying the oil. Avoid getting it on your lips or into your mouth.
